COIN-OPERATED LOCK.

Application filed January 31, 1921, Serial No. 441,135. Renewed August 31, 1922. Serial No. 585,561.

To all whom it may concern:

Be it known that I, MARK N. SMITH, a cit izen of the United States, and a resident of Yonkers, in the county of Westchester and State of New York, have invented a new and useful Coin-Operated Look, of which the following is a specification.

My invention relates to coin operated locks and its principal object is to provide a lock of this character, principally adapted. for use in public places such as toilets or in other places where a small charge is usually made for the use of such places.

A further object of the invention is to provide a lock which may be operated by coins of a prei'letermined denomination and which cannot be operated by slugs of less weight and diameter than the coin or other fraudulent means.

It is also an object of the invention to provide a coin operated lock having means for indicating whether or not the toilet or other public place is in use, and which, when in use, will prevent a second coin from being inserted therein.

Still another object of the invention is to provide a lock of this character which may be operated by the attendant without the use of a coin.

Vith the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, construction and arrangement of parts and operations to be more fully described, claimed and illustrated in the accompanying drawings wherein:

Figru'e l is a rear elevation of the lock, parts being browen away;

Figure 2 is a face View of the removable rear wall of the lock and the lock parts carried thereby;

Figure 3 is a view partly in elevation and partly in vertical cross section of the lock assembled Figure 4: is a top plan view of the lock;

Figure 5 is a bottom plan view of the same;

Figures 6, 7 and 8 are perspectives of various elements embodied in the invention;

Figure 9 is a fragmentary elevation of the lock section disclosed in Figure 1;

Figure 10 is a front elevation of the latter, having parts broken away;

. Figure 11 is a side elevation of the lock in operative position; and

Figure 12 is a perspective of the attendants key used in connection with the invention.

Referring in detail to the drawings wherein similar characters of reference designate similar parts throughout the several views, the numeral 5 designates a door to which my improved lock is applied. Mounted upon the outer face of the door 5 is a plate 6 carrying an upturned flange 7 at its upper edge which is spaced from the door Passing transversely through the door 53 from the inner face thereof is the shaft 8 of a door knob 9. The inner end of this shaft 8 extends within a casing 10 secured to the outer face of the plate 6. Arranged in this casing 10 and operatively connected with the shaft 8 is a spring look mechanism 11. One end of this shaft 8 projects through the casing 10 and fixed thereto is a vertically disposed longitudinally curved. arm 12 which is for a purpose to be herein-- after specified.

The numeral 13 designates a casing which is open at the rear thereof and is formed with a do\vnturned flange let at the rear of its upper end which is removably held between the flange 7 and the door A bar 153 extends transversely across the casing ad jucent its lower end and is secured to the door by screws or other fastenings l6.

Mounted in the casing 13 is a conventional lock designated in its entirety at 17 and includes a swinging spring held menu ber 18 and a sliding looking bolt 19 movable transversely of the casing 13. As is clearly shownin Figure 8, the locking bolt 19 is provided with a slot 20 at its rear end having pivotal and slidable connection with the swinging member 18. The shaft 21 of doorknob 22 extends transversely through the casing 13 from the outside thereof and is fixed to rotate with the swinging member 18. Thus, upon rotation of the door knob 22, the swinging member 18 will be swung or rocked to retract the locking bolt 19.

As is shown in Figure 2, the lock mechanism 11 includes a spring held swinging member 23 identical to the swinging meru ber 18 and which carries, at its upper end,

a laterally disposed pin 24 which projects within the slot of the looking bolt 19.

It will thus be obvious that upon rotation of is provided in the top of the casing 13 and is disposed in vertical alinement with the chute or coin guide 25.

'Pivoted to the plate 27, at one edge thereof, is a trip 31, the forward end of which is normally disposed in "the path of the coins passing through the coin chute or guide The opposite end of this trip 31 is weighted as 32 so that the trip will be normally disposed in the annular position shown in Figure 1. Formed upon the inner face of the part 32 is a pair of laterally disposed spaced lugs 33 whose opposed faces are beveled to present divergent surfaces 34 as shown in Figure 7.

Vertically movable in the casing 13 is a stem or shank 35, carrying at its upper end, a rectangular head or locking element 36 which normally engages the swinging member 18 and locks the'sameagainst movement. The lower end of this stem or shank is formed with a right angularly disposed foot 37 which is engaged between the spaced lugs 33 for pivotal movement. In order to limit the pivotal movement of the trip 31 in one direction, an abutment 32 is formed upon the forward wallf of the casing 13 above the point of pivotal'connection of this trip 31 with the plate 27 and is provided with a beveled lower wall 33 with which the part 32 of the trip 31 abuts.

Pivoted to the plate 27, at its opposite edge. is a finger or coin holding element 38, the lower end of which projects downwardly at an angle and is in the path of the coins passing through the chuteor guide 25. The upper'end of this finger or coin holding element '38 is pivotally connected with the lo'cking bolt :19 as indicated at 39.

From the disclosure thus far given, it follows that when a coin is inserted in the slot 30, it passes downwardly through the chute or guide .25 and engages the forward end of the trip 31, raising the latter to the dotted line position and lifting the "stem or shank 35 to a position where the locking element 36 will not engage the swinging member 18; the coin continuing downwardly is engaged by the finger 38 and is held in this position by the finger 38 and the trip 31. The knob 22 may be now rotated to retract the locking bolt 19. This moves the finger 38 away from the coin and the latter drops to the bottom of the casing, and the trip 31 and locking element 36 return to their normal position.

. Horizontally and longitudinally movable in a guide-way 40 at the upper end of'the casing 13 is a block or carriage 41 carrying a laterally disposed pin &2 at one end thereof. Carried upon the upper face of this blookor carriage 41 is suitable indicia 4C3 which reads, in'this instance, In Out. The top wall of the casing 13 is provided with a' sight opening tt with which the words In or -Out are adapted to register.

Carried by the inner end of the shaft 21 is an upstanding arm 45 having its upper end engaged with the pin 42. Thus, after the lock has been operated, as hereinabove described, the rotation of the shaft 21 will move the arm 45 forwardly to move the block or carriage 41 to a position where the word ln will register with the sight opening.

The upper end of thearm 12 disposed atthe opposite end of the casing and is in the path of the pin 12 when the block or carriage is in its advanced position. Thus, upon rotation of the shaft 8 the arm 12 will engage the pin 42 and move the block or carriage to the position shown in Figure 1 and in which position the word Out will register in the sight opening.

A cover plate 46 is arranged'inthe casing 13 to overlie the various elements'to retain the same in their respective positions.

In order that anattendant or other authorized person may operate the look without the aid of a coin. 1 provide a vertically movable stem 47 which passes through a vertical opening or guide 48 of a cross bar 19 in the casing 13. Formed within the casing 13 in alinement with the stem 4:? is a rectangular casting 50 having a vertical bore 51 which slidably receives the lower end of the stem 4-? and which registers with a key opening 52 in the bottom wall of the casing 13. This bore 531 is formed with a laterally disposed recess 53 at its lower end.

The stem 47 carries a collar 54 which-normally rests on the casting 50 and supports this stem in a position where its upper end will touch the weighted end of'the trip 31.

The key designated at and shown in Figure 12 includes lugs 56 that are disposed at right angles to each other. In unlocking the look by means of this key, the latter is inserted into the bore 51 andin which position the lower lug 56 will be disposed. in the recess The key is then rotated a quarter turn so that this lug will pass out of the recess 53 and when inthis position, the key 55 is raised vertically to lift the stem 47 which rocks the trip 31 on its pivot and raises the locking element 36.

In order to gain access to the interior of the casing for collecting the coins'therefrom, the casing 13 is provided with a circular opening 57 normally closed by a removable door 58 carrying a lock 59, the locking bolt of which engages in a recess 60 in the bar 49, while, at its lower end this door or closure carries a lip 61 engageable behind the forward wall of the casing.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is
